[0001] The invention relates to the technical field of air conditioning structures, and in particular to an air outlet structure of a fan and an air conditioner thereof. Background Art

[0002] With the development and progress of science and technology, many air conditioners have added fresh air treatment devices, which introduce outdoor air into the room through the centrifugal fan inside the air conditioner. The principle of micro-positive pressure is used to expel turbid indoor air, continuously dilute and replace the indoor air, and achieve the purpose of purifying the indoor air.

[0003] However, the air outlet method of the prior art generally only sets one air outlet along the air outlet direction of the centrifugal fan. Some application scenarios will affect the user's experience of fresh air. For example, for fresh air cabinets, they are generally installed in the corners of indoor walls. In order to reduce the noise of fresh air, the fan outlet is set on the wall side of the rear part of the whole machine, then the fresh air will be blown directly to the corner or the rear wall, which is not conducive to the introduction of fresh air to flow indoors; when the fan outlet is set on the left or right side of the whole machine, due to the limited installation position of the air conditioner, the fresh air may also be blown directly to the wall, which is not conducive to the flow of fresh air indoors, which will affect the user's experience of the fresh air function of the air conditioner. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an air outlet structure of a fan to solve the problem in the prior art that a centrifugal fan is only provided with one air outlet, and when the cabinet is placed in a corner of a room, the air outlet is limited due to the arrangement of the air outlet on the cabinet, which is not conducive to the flow of fresh air in the room.

[0005] To achieve the above object, the present invention adopts the following technical solution: an air outlet structure of a fan, comprising:

[0006] A first air outlet, wherein the first air outlet is arranged on the air outlet section of the fan, and a first damper is movably provided at the first air outlet;

[0007] A second air outlet, wherein the second air outlet is arranged on the air outlet section of the fan and the central axis of the second air outlet is arranged perpendicular to the central axis of the first air outlet, and a second air door is movably provided at the second air outlet;

[0008] The airflow reversing linkage regulating component is arranged between the first damper and the second damper, and is used for controlling the opening and closing of the second damper in a linkage manner when adjusting the opening and closing of the first damper.

[0009] The present invention also adopts the following technical solution: an air conditioner, comprising the above-mentioned air outlet structure of a fan.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The air outlet structure of the fan is that when the air outlet is placed in the indoor corner, since the first air outlet and the second air outlet are vertically arranged on the air outlet section of the fan, at least one of the first air outlet and the second air outlet will not be restricted. The opening and closing of the first air outlet and the second air outlet can be adjusted in linkage through the cooperation of the airflow reversing linkage adjustment component to open the unrestricted air outlet, so as to adjust the use state of the air outlet according to the actual use scenario to meet the use needs;

[0012] 2. When the air conditioner is placed in a corner of a room, since a vertically arranged first air outlet and a second air outlet are formed on the air outlet section of the fan, at least one of the first air outlet and the second air outlet will not be restricted. The opening and closing of the first air outlet and the second air outlet can be adjusted in a linkage manner through the cooperation of the airflow reversing linkage adjustment component to open the unrestricted air outlet, so as to adjust the usage status of the air outlet according to the actual usage scenario to meet the usage requirements.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below through specific embodiments:

[0020] like Figure 1 , Figure 2 as well as Figure 3 As shown, an embodiment of the present invention provides an air outlet structure of a fan, including a first air outlet 1, a second air outlet 2 and an airflow reversing linkage adjustment component;

[0021] Wherein, the first air outlet 1 is arranged on the air outlet section of the fan, and a first damper 3 is movably provided at the first air outlet 1;

[0022] The second air outlet 2 is arranged on the air outlet section of the fan and the central axis of the second air outlet 2 is arranged perpendicular to the central axis of the first air outlet 1. A second damper 4 is movably provided at the second air outlet 2.

[0023] The airflow reversing linkage adjustment component is arranged between the first damper 3 and the second damper 4, and is used for controlling the opening and closing of the second damper 4 in a linkage manner when adjusting the opening and closing of the first damper 3.

[0024] When the fan's air outlet is placed at a corner of a room:

[0025] Since a vertically arranged first air outlet 1 and a second air outlet 2 are formed on the air outlet section of the fan, at least one of the first air outlet 1 and the second air outlet 2 will not be restricted. The opening and closing of the first air outlet 1 and the second air outlet 2 can be adjusted in a linkage manner through the cooperation of the airflow reversing linkage adjustment component to open the unrestricted air outlet, so as to adjust the usage status of the air outlet according to the actual usage scenario to meet the usage requirements.

[0026] In this embodiment:

[0027] Specifically, the airflow reversing linkage adjustment component is used to control the opening and closing of the second damper 4 in linkage when adjusting the opening and closing of the first damper 3 , and the opening and closing state of the first damper 3 is opposite to the opening and closing state of the second damper 4 .

[0028] That is, when the first damper 3 is opened to make the first air outlet 1 conductive, the second damper 4 is closed by the airflow reversing linkage adjusting component during the process of opening the first damper 3, and the second air outlet 2 is sealed by the second damper 4, and the first air outlet 1 can be used according to actual conditions; when the first damper 3 is closed and opened to make the first damper 3 seal the first air outlet 1, the second damper 4 is opened by the airflow reversing linkage adjusting component during the process of closing the first damper 3, and the second air outlet 2 is conductive, and the second air outlet 2 can be used according to actual conditions.

[0029] like Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, according to another embodiment of the present invention, a wind outlet structure of a fan, wherein the first damper 3 is slidably arranged at the first air outlet 1, and the second damper 4 is rotatably arranged at the second air outlet 2; the airflow reversing linkage adjustment component includes a first limit adjustment part, a second limit adjustment part and a linkage adjustment part;

[0030] Wherein, the first limit adjustment part is arranged on the first damper 3;

[0031] The second limit adjustment portion is disposed on the first damper 3 and is spaced apart from the first limit adjustment portion along the moving direction of the first damper 3;

[0032] The linkage adjustment part is connected to the second damper 4 and is located between the first limit adjustment part and the second limit adjustment part;

[0033] When the first damper 3 moves, the first limit adjustment part and the second limit adjustment part cooperate to drive the linkage adjustment part and drive the second damper 4 to rotate.

[0034] In this embodiment:

[0035] For example, the first air outlet 1 is arranged upward, the second air outlet 2 is arranged to the left, the first air door 3 slides in the horizontal direction to seal or conduct the first air outlet 1; the top of the second air door 4 is rotatably connected to the second air outlet 2 through the rotating shaft 8, and the second air door 4 is arranged vertically when sealing the second air outlet 2. Figure 2 When the first damper 3 is slid to open the first air outlet 1, the second limit adjustment part cooperates with the linkage adjustment part to rotate the second damper 4, and the second damper 4 seals the second air outlet 2; Figure 3 When the first damper 3 is slid in the reverse direction to seal the first air outlet 1 , the first limit adjustment part cooperates with the linkage adjustment part to make the second damper 4 rotate in the reverse direction, and the second air outlet 2 is connected.

[0036] Based on the above scheme:

[0037] The first limit adjustment part is a first limit push plate 5 fixedly connected to the first damper 3 , and the first limit push plate 5 is formed with an adjustment inclined surface that cooperates with the linkage adjustment part.

[0038] Specifically, the first limit push plate 5 can be integrally formed or welded on the side of the first damper 3 facing the first air outlet 1, and a weight reduction hole can be opened in the middle of the first limit push plate 5; when the first damper 3 is slid to open the first air outlet 1, the adjustment slope on the first limit push plate 5 cooperates with the linkage adjustment part to rotate the second damper 4, and the second damper 4 seals the second air outlet 2.

[0039] The second position limiting adjustment part is a second position limiting push plate 6 fixedly connected to the first damper 3, and the free end of the second position limiting push plate 6 cooperates with the linkage adjustment part to be linked.

[0040] Specifically, the second limit push plate 6 can be integrally formed or welded on the side of the first damper 3 facing the first air outlet 1; when the first damper 3 is slid in the reverse direction to seal the first air outlet 1, the second limit push plate 6 cooperates with the linkage adjustment part to make the second damper 4 rotate in the reverse direction, and the second air outlet 2 opens.

[0041] The linkage adjustment part is a linkage adjustment block 7 connected to the rotation connection of the second damper 4, and the linkage adjustment block 7 is located between the first limit push plate 5 and the second limit push plate 6 for linkage.

[0042] Specifically, the linkage adjustment block 7 can be integrally formed or welded at the rotation connection of the second damper 4, and the linkage adjustment block 7 and the second damper 4 are arranged in the same plane, and the linkage adjustment block 7, the second damper 4 and the rotating shaft 8 cooperate to form a swing rod structure centered on the rotating shaft 8. When the first damper 3 is slid to open the first air outlet 1, the first damper 3 moves for a period of time first, and then the adjustment slope on the first limit push plate 5 contacts the linkage adjustment block 7 to make the second damper 4 rotate around the rotating shaft 8, and the second damper 4 seals the second air outlet 2; when the first damper 3 is slid in the reverse direction to seal the first air outlet 1, the first limit push plate 5 is disengaged from the linkage adjustment block 7, and then the first damper 3 moves for a period of time, and then the second limit push plate 6 contacts the linkage adjustment block 7 to make the second damper 4 rotate in the reverse direction around the rotating shaft 8, and the second air outlet 2 is opened.

[0043] It is worth noting that: the adjustment slope is arranged along the moving direction of the first damper 3 and when the first limit push plate 5 is abutted to make the linkage adjustment block 7 rotate to drive the second damper 4 to open, the rotation connection point of the second damper 4 is located in the middle of the adjustment slope and at this time, the projection of the free end of the linkage adjustment block 7 on the second limit push plate 6 is located in the middle of the second limit push plate 6. Figure 3 As shown, when the first air outlet 1 is sealed and the second air outlet 2 is fully opened, the free end of the linkage adjustment block 7 is located at the high point of the adjustment slope, the rotating shaft 8 is located in the middle of the adjustment slope, and the height of the free end of the linkage adjustment block 7 is higher than the height of the second limit push plate 6. The design here is to ensure that during the movement of the first damper 3, the linkage adjustment block 7 can maintain a good rotation between the first limit push plate 5 and the second limit push plate 6 along with the movement of the first limit push plate 5 or the second limit push plate 6, so that the linkage process can be carried out stably.

[0044] In order to further improve the stability of the second air door 4 during the opening and closing process, a limiting rib 9 arranged opposite to the rotating shaft 8 can also be provided on the side wall of the second air outlet 2, so that when the second limiting push plate 6 drives the second air door 4 to rotate to seal the second air outlet 2, the free end of the second air door 4 is restricted by the limiting rib 9 and will not cross the second air outlet 2. The second air door 4 can maintain a good seal on the second air outlet 2.

[0045] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, according to another embodiment of the present invention, in the air outlet structure of the fan, the first damper 3 is slidably arranged at the first air outlet 1 through an opening and closing control component, and the opening and closing control component includes a rack 10 and a gear 11;

[0046] Wherein, the rack 10 is arranged at the first air outlet 1 along the sliding direction of the first air door 3;

[0047] The gear 11 is rotatably disposed on the first damper 3 and meshes with the rack 10 .

[0048] In this embodiment:

[0049] The rack 10 is specifically fixed on the volute of the fan, and a drive motor 12 is fixedly connected to the first damper 3 by bolts. The drive motor 12 is connected to the gear 11 to drive the gear 11 to rotate forward or reverse. The rotating gear 11 cooperates with the rack 10 to slide the first damper 3 to make the first air outlet 1 conductive or sealed.

[0050] In order to make the sliding of the first damper 3 more stable, a guide rail 13 arranged along the sliding direction of the first damper 3 is further provided between the first damper 3 and the first air outlet 1 .

[0051] Here, there are two guide rails 13 distributed on both sides of the first damper 3 to guide the movement of the first damper 3 so that the movement and adjustment of the first damper 3 are more stable.

[0052] According to another embodiment of the present invention, an air conditioner includes an air outlet structure of a fan in any of the above embodiments.

[0053] Here: the fan may be a centrifugal fan, and the air outlet structure of the fan is arranged on the air outlet section of the centrifugal fan. However, the air outlet structure of the fan is not limited to being installed only on the air outlet section of the centrifugal fan, and may also be installed in other suitable environments for use according to needs.

[0054] When adjusting:

[0055] 1. When the first air outlet 1 needs to be turned on:

[0056] The driving motor 12 is operated by the button 1 on the air conditioner or the button 1 on the remote control matched with the air conditioner, and the driving motor 12 drives the gear 11 to rotate, and the first damper 3 slides through the transmission of the rack 10, the first air outlet 1 is connected, and the second limit push plate 6 cooperates with the linkage adjustment block 7 to rotate the second damper 4, and the second air outlet 2 is closed.

[0057] 2. When the first air outlet 1 needs to be closed:

[0058] The driving motor 12 is made to run in the reverse direction by pressing the button 2 on the air conditioner or the button 2 on the remote control matched with the air conditioner. The driving motor 12 drives the gear 11 to rotate in the reverse direction. The first damper 3 is made to slide in the reverse direction through the transmission of the rack 10. The first air outlet 1 is sealed, and the first limit push plate 5 cooperates with the linkage adjustment block 7 to make the second damper 4 rotate in the reverse direction, and the second air outlet 2 is opened.

[0059] This air conditioner only uses one driving motor 12 in conjunction with an airflow reversing linkage adjustment component and other structures to achieve the opening and closing conversion between the two air outlets. It can independently switch the airflow direction of the fan according to the actual use scenario of the whole machine to ensure the actual use effect of ventilation; and its cost is relatively low.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
